VIDIOC_QUERYSTD and VIDIOC_G_STD ioctls are currently not supported in the FSL VIU driver. The decoder subdevice driver saa7115 extended by previous patch supports QUERYSTD for saa7113, so we add the appropriate ioctls to the VIU driver to be able to determine the video input's standard....
在进行V4L2开发中,常用的命令标识符如下: (1)VIDIOC_REQBUFS:分配内存; (2)VIDIOC_QUERYBUF:把VIDIOC_REQBUFS中分配的数据缓存转换成物理地址; (3)...VIDIOC_CROPCAP:查询驱动的修剪功能; (9)VIDIOC_S_CROP:设置视频信号的边框; (10)VIDIOC_G_CROP:读取视频信号的边框; (11)VIDIOC_QBUF:把数据从缓存中读取...
